# Dubai Shopper · PriceWatch (prices.brainy.ae)

> Independent daily price comparison for groceries in Dubai (UAE). Prices are observed on the
> websites of Dubai supermarkets and delivery sites. Exact products and explicit equivalents are labelled separately. Amounts are in
> AED including VAT. Delivery fees come from public store rules or are marked unknown (never assumed to be 0).

## What the site covers
- A fixed basket of everyday products priced across multiple chains (online sites and in-store data), with a daily
  ranking and price history: https://prices.brainy.ae/ and https://prices.brainy.ae/products.html
- A catalogue of ~200 products (exact items and explicit equivalents) with per-store offers, used by the list
  comparison: https://prices.brainy.ae/grocery-list.html (paste a list, upload a photo or CSV; compare per store)
- Recurring baby costs (diapers and formula): https://prices.brainy.ae/baby-essentials.html
- Pack value comparison (price per 100 g / 100 ml / piece): https://prices.brainy.ae/pack-value.html
- Restaurant delivery fees by neighbourhood (Deliveroo): https://prices.brainy.ae/delivery.html
- Live online price references (Google Shopping, indicative): https://prices.brainy.ae/search.html

## Rules the comparisons follow
- Whole packs are bought; quantities are never split across stores in a single-store answer.
- Stores are ranked on the same comparable subset; partial coverage and provisional recommendations must be preserved.
- Unknown delivery fee is unknown, not free. Free-delivery thresholds and minimum orders are applied when published.
- Online references from Google Shopping are indicative and never mixed into the verified ranking.
